Player Not connecting to Bridge Controller

[SeanSixeas]

I have A Rasp Pi3 as my main controller(Player). I have 3 Kulp boards and on3 Rasp Pi bridge to a F16v3 as remotes. The Pi to F16 work fine together, But I cant get my Player to communicate to the F16V3. I keep getting  Error, Cannot Ping DDP channel data target 192.168.45.3 F16V3. below are some screen shot of my set up.

What are the IP addresses of all the devices?
How are you connecting to your Pi that you are using as a bridge? Wi-Fi?
When using a Pi as a bridge, you typically have the interfaces on different networks and because of that, you have to create some sort of routing to tell your computer how to get to your device. There are 3 basic ways to do that.
